Application filed April 8, 1905. Serial No. 254,579-

To all whom/zit may concern:

Be it known that we, EDWIN NORTON, residing at New York, in the county of New York and State of New York, andVIoToR CHARTENER, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, citizens of the United States, have invented or discovered new and useful Imrovements in Work-Rever ing Mechanism 0r Rolling-Mills, of which the following is a specification.

Our invention relates to rolling-mills, and more particularly to mechanism for reversing the Work between successive stands of rolls.

It is the object to provide a straightaway feeding mechanism for use with universal or other t es of rolling-mills wherein the work is fed H1 the same direction through the rolls, which always run in the same direction and which need thereby be but two high, the work being reversed before entering the passes of the successive rolls or of such rolls as itis deemed desirable to reverse the work.

We have discovered that when metal is rolled by passing the same end foremost through the rolls the molecules of the iron are strained or displaced in such a manner as not to produce as desirable and as uniform quality of plates aswhen the metal is fed during a portion of the rolling process with one end foremost andduring another portion thereof with the opposite end foremost. Accordingly, we have devised a table to which the metal is fed by one set of rolls and by which it is turned end for end and fed into the next set of rolls. We have illustrated means for reversing the feeding means carried by the table and for reversing the table; but the specific means shown for doing these things, as well as the construction of the table itself, may be departed from without sacrificing our invention.

Referring to the. drawings which accompany this specification, Figure 1 is a plan of the preferred form of our invention, details being omitted tolavoid confusion; 1, a detail showing the driving connection between the shafts and 13; Fig. 2., an end elevation of one of the tables by which the work is reversed and transferred from one set of rolls to another; Fig. 3, aplan view-of one of said tables, a part being broken away to show one of the side gages; Fig. 4, an end Shaft 16.

- Referring now to Figs. 1 to 8, 1 represents the vertical rolls, and 2 the horizontal rolls, of a universal rolling-mill. We have shown three sets of rolls of this character; but it is to be understood that any number of sets.

,A and A of rolls we place one of our reversing feeding-tables B and between the sets A and A of rolls another of .our said tables B. To the right of the set A of rolls We have shown a portion of a stationary table B which forms no part of the present invention, but is shown for the purpose of showing a combination 'with which the reversing-tables may be connected. As each table'B and B is constructed the same, a description of one will be suificient. The table, as B, has two side plates 3 and 4, secured together by the cross-bars 5 or otherwise and mounted centrally on the horizontal trunnions 6 and 7, which turn in bearings on the standards or housings 8 and 9.

To the trunnion 6 is coupled the shaft 10, having secured to its outer end the wormwheel 1 1, driven by the worm '12 on theshaft 13, the latter being common to the worms whichdrive the worm-wheels 11 of the tables B and B. The shaft 13' is provided with the clutch member 14, which may be of any approved type and is cooperable With the corresponding clutch member 15 onythe The latter is provided with the the shaft 19', which in turncar'ries the gearwheel 20, meshing with the pinion 21 0n the shaft of. themotor 22. The trunnion 6 is provided with a long loose pinion 23, whose inner, portion meshes with the spur-gear 24,

lying beneath the same and secured to the shaft 25, supported in the standard 8; The shaft 25 has secured to its outer end the bevel-wheel 26, in mesh with the two bevelwheels 27 and 28, loose on the shaft 19. Be

The gages consist of plates 47, movable transverscly. of the table by the screws 48, which are threaded throiigh the plates 3 and 4 and bear against the outer sides of the plates 47. The gages are, held from inward movement by the bolts 49, having their heads in recesses in the inner faces of the gages and their bodies in holes through the plates 3 and 4.

On .the bolts are the nuts 50, which bear against the said plates.

'51 represents ja1n-nuts on the screws 48.

The set B of the feed-tables may rotate, as do the tables B and B; but'we have shown a stationary table qWlt/h one end broken 0 Theshaft 52, driven in any manner,has thereon the gear-wheel 53, meshing with the wheel 54 on the roller 55 which has thereon the bevel-gear 56, in mesh with the bevel-gear 57 on the shaft 58, provided with bevel-gears to 'drive. the other rollers of the table, as shown. The set B is notessential for all purposes, as it, as well as the set B, may be omitted or their-placesupplied by other devices; I

The operation is as follows: T he itable B is supposed to stand as shown in Fig. 2, where the work is supposed to be coming from the left.' The stop at the left, being below the pass, is horizontalwith the fingers .42 thereof 1n the recesses 46 of the adjacent roller 32 or The stop at the right, being above the pass, is pendent and liesdirectly across the pass, with its'fingers against the front side of The motor 22 is set The work, which may be supposed to be packs of hot plates, is fed through the rolls A and into the pass between the upper and lower rollers of the table B. The pack will be stopped by thestop 37 at the farther end of the table, the rear end .of the pack lying above the stop atthe'other end of the table.

The clutch .mernber cause the shaft 16 to drive the shaft 13, which 14 is now operated to in turn rotates through worms 12 and wormwhels 11, the shaft 10. causing a revolution of the tables B and B, which are stopped at a semirevolution by means of the ally. The feed-rolls 'of the tables B and B, which'were preferably stopped by hand or automatically when the pack was fed into the table B, are reversed by moving, the rod 31 so as to drivethe wheel26 1n t e-dlrectlon .opp'osite to its former rotation. This causes a reverse rotation of the rollers in the tables B and B and a consequent feeding of the pack in the table B into the pass between the rolls'of the set A, which in tui'nfeeds the pack into the table B, which receives them the same as the table B did. As the pack of clutch A member 14, operated by hand or automatlcplates left the table B the stop, which' was previously supported in a horizontal position by the pack, immediately swings down into the vertical position to stop a second pack of plates, which we may suppose has been fed to the walls A and is entering the table B while the previously-rolled pack is entering the table B. As soon as the packs are within the tables B and B the tables are reversed as before, and the pack in table B is fed to the rolls A and into the'table B, and thepack in the table B is fed to the rolls A and to the table B whence they pass to such other mechanism or place as is deemed best.

We do not restrict our reversing-table to the construction shown and described or to its being an element of the combination with which it has been shown and described, as it "may be variously constructed and used without departing from the principles thereof. We desire our claims to be given the largest scope that the state of the art will permit irrespective of the mechanical elements andcombination we have used.

Having described our invention, we claim-- 1. In a rolling-mill, two sets of rolls, a table arranged between them and capable of receiving the Work alternately at opposite ends ,stops arranged to limit the feed of the work from each end of the table, and means for reversing the table end for end, the stop at the feedin -in end of the table nearest the first set of ro ls adapted to permit the entrance to the table of a second piece of work from said first set of rolls and the stop at the opposite end of the table being constructed'to move so as to stop the incomingwork after the discharge of the outgoing wor 2. A table arranged to receive work alternately at opposite ends, means carried by the table for feeding the work, means for reversing the table so that the work may be fed from the table from the feeding-in end thereof, means for reversing the feeding means, and means to limit the feed of the work on the table.

3, A vertically-reversible table having thereon feeding-rollers arranged to form a pass, means for reversing the rotation of said rollers, and gravity-stops at each end of the table arranged to enter the said pass from opposits sides.

4. In a rolling-mill, a rotatable table having therein a Work-feeding pass and a stop at each end of the pass, the stop normally at the feeding-out end of the table tendingto close said pass but restrained from doing so by the work while therein.

5. In a rolling-mill, a table rotatable in a vertical plane havin therein a work-feeding passage and a mova le gravity-stop for said passage at each end thereof, one mounted above and one below the same.

6. In a rolling-null, a table rotatable in a vertical plane having therein a work-feeding passage, a pivoted gravity-stop for said passage at each end thereof, one mounted above and the other below the same.
